It’s 8K per eye and to meet latency expectations right now you’d need to send the whole 180/360 video with enough resolution through it’s entirety so that there’s always enough pixels within the spherical polygon the eye frustrums create. Far more than an 8K feed and in particular I don’t know of any cameras capturing at that resolution?

360 video is also quite nauseating for people as it has no positional component (e.g. moving your head forward brings the scene with it). What we really want are streaming light fields.

VR180 6-8K video at 90hz is such a visible improvement compared with lower quality formats on Quest 2. But there is so little content available at high resolutions and high frame rates. I just hope this will improve (at least slowly) in time.
